Vehicle Data Transmission Redundancy via Channel Set Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle communication systems lack effective redundancy designs, leading to data loss and increased network load when a network channel fails, which affects vehicle operation and user experience.
Innovation Solution
A communication method that determines the message type of a first message and transmits it through either a first channel set or a second channel set based on the network status, ensuring data redundancy and maintaining network stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is transmitted through multiple networks to ensure redundancy, then data reliability is improved, but network load increases and communication quality deteriorates
Solution Approach 1:
The patent segments messages into different types (first type and second type) with different redundancy requirements. First type messages use single-channel transmission while second type messages use multi-channel transmission, allowing the system to balance reliability and network load based on message importance
Solution Approach 2:
Different transmission strategies are applied to different message types. Critical messages (second type) receive enhanced redundancy protection while non-critical messages (first type) use basic transmission, optimizing network resource allocation based on local message requirements
2Loss of information
If communication redundancy is implemented, then data loss is prevented, but network channel load rate increases
Solution Approach 1:
The patent applies partial redundancy only where necessary. Instead of replicating all messages across multiple channels, it selectively applies redundancy only to second type messages that require it, avoiding unnecessary network load while preventing data loss for critical communications
3Reliability
If all network channels transmit all messages, then data redundancy is maximized, but network stability decreases due to excessive load
Solution Approach 1:
The transmission strategy dynamically adapts based on message type. The system determines which channel set to use (first channel set with one normal channel or second channel set with multiple normal channels) based on the message type, allowing flexible adjustment between redundancy and network stability

AI summary
Embodiments of the present disclosure provide a communication method and a related apparatus, which are applied to the field of vehicle communication technologies. In the embodiments of the present disclosure, a first message that needs to be transmitted out through a first network channel can be obtained. When a network status of the first network channel is abnormal, a message type of the first message is determined. If the message type of the first message is a first type, the first message is transmitted through a first channel set. If the message type of the first message is a second type, the first message is transmitted through a second channel set. A quantity of network channels included in the first channel set is less than a quantity of network channels included in the second channel set. In this way, data redundancy can be ensured and a load rate of each network channel does not increase sharply, thereby improving stability and reliability of data transmission, and effectively improving user experience.
